  • High temperature resistant gaskets for BS 3063 Table D and Table E flanges.
  • Suitable for use with potable water.
  • Made from industrial-grade silicone rubber.
  • Cut to size in our Australian facilities to suit the precise requirements of BS 3063.

Silicone Rubber Gaskets are a popular choice for sealing flanges in applications with elevated temperatures.

This page lists our range of 3mm thick Red Silicone Gaskets to suit BS 3063 Table D and Table E flanges in the Ring Face configuration (without bolt holes). They are quality rubber gaskets, cut to size in Australia, with a maximum operating temperature of 260°C and a range of other performance benefits. 

Sealing Capabilities of Red Silicone Rubber Gaskets.

Our Red Silicone Rubber is a premium-quality, industrial grade Silicone Rubber Sheet with excellent sealing properties. This rubber has excellent temperature resistance, very good electrical insulation properties and wide-ranging chemical resistance. These, and other properties, are expanded on more below:

Food Grade and Potable Water Approved.

Washers, gaskets and seals cut from our Red Silicone Rubber inherit this materials food and potable water certification. Red Silicone Rubber Gaskets from Swift are made from food grade rubber which allow them to be used in sealing equipment that will have direct contact with food (as per FDA and EU standards) and for sealing potable (drinking) water (as per WRAS).

This rubber also carries certifications for several other applications which are detailed more on the attached technical data and over on the specifications tab.

Excellent Heat and Cold Temperature Resistance.

Seals made from our Red Silicone Rubber will withstand ongoing exposure to temperatures between -60°C and +230°C as well as short-term spikes to 250°C.

This is important as most other rubbers (Viton/FKM is the other exception) simply will become brittle and crack well before -50°C and will exhibit serious degradation before 160°C. Silicone doesn't and maintains excellent flexibility and sealing performance. An important attribute for high or low temperature seals.

Excellent Sealing Characteristics.

Silicone Gaskets are often selected because of this rubber excellent sealing performance. All the gaskets featured on this page are made from 60 Shore A Durometer Rubber sheet and have excellent compression, recovery and mechanical strength.

This results in flange gaskets which are very long lasting and offer reliable sealing performance.

Flange Gaskets to Suit BS 3063 Size Info.

This page lists ring types gaskets. This style of gasket is designed to sit inside the bolts of the flanges and is known by quite a few names, including:

  • RF Flange Gaskets.
  • IBC Gaskets (Inner Bolt Circle).
  • Raised Face Gaskets (as they are often used on raised face type flanges).
  • Ring Face Gaskets.

Theseg askets are all cut to suit BS 3063 Flanges in either Table D or Table E configurations (the two most common). In almost all pipe nominal bores (except 150NB, 200NB & 300NB) there’s no difference in gasket size between Table D or Table E (the gasket fits both) when using ring type gaskets.

For those where there is a difference, both Table D and Table E variations are offered separately.
